Men of uncertainty are without identity.

Is it possible to be without identity?

Paul shows how someone can be truely without identity ... 

That is ... without understanding (click here), knowing nothing ... lonely ... lost ...

Clueless!

Paul was talking to some intelligent people

Talking to the men of Athens (anthens means uncertainty) Paul indicates that these philosophical-minded intellectuals, who could not wait for the next sophist-poet to recite a work of art or religion, had made an altar for an unknown God. 

These Greeks were renowned as intellectuals. They contemplated the fine art of living along with life itself all day long through intellectual reasoning. They really tried to cover all bases. And so made provision for an unknown God just in case the might have missed one.

So, Paul makes the unknown known

Paul used their own approach and background as a departure for bringing the Gospel of Jesus.

יהוה that made the world and all things therein, seeing that he is Ruler of heaven and earth, dwelleth not in temples made with hands;

Neither is worshipped with men's hands, as though he needed any thing, seeing he giveth to all life, and breath, and all things;

And hath made of one blood all nations of men for to dwell on all the face of the earth, and hath determined the times before appointed, and the bounds of their habitation;

That they should seek Him, if possibly they might feel after him, and find him, though he be not far from every one of us:

For in him we live, and move, and have our being; as certain also of your own poets have said, For we are also his offspring. Act 17:24-28

In verse 28 (quoted last above) Paul quotes the Greek poet and philosopher Aratus, and shows how his words are applicable to man through Jesus.

... and it's not unlike today

The result of this message was rather comparable to the reaction we usually get today when uncertain people hear the Gospel of Grace. Some will have nothing of it. Others will desperately seek to hear more.

Jesus brings certainly 

He is your identity.

In Him we find Life!

In Him we are moved (compassion)!

You know only who you are through Him!

... and the Spirit of Truth will reveal this to anyone ... even an uncertain philosopher with no identity!

HalleluYAH!
